$12.26Graco 17J393 Fitting Tube Straight 1/4NPT delivers reliable performance in demanding fluid delivery setups. Precision machining ensures optimum sealing and consistent dimensions throughout the stainless steel body. Corrosion-resistant properties enable operation under high pressure and exposure to harsh coatings and chemicals. Its robust build integrates seamlessly into pumps, manifolds, and fluid lines found in industrial coating and adhesive dispensing installations. End users benefit from reduced downtime thanks to leak-free joints and simplified replacement procedures.
Manufacturing employs CNC turning and milling to achieve tolerances within 0.01 mm, guaranteeing repeatable alignment in high-pressure systems. Operating temperature range spans -20 °C to 150 °C without material degradation. An electropolished finish reduces surface roughness and enhances resistance to corrosive agents. Each module undergoes hydrostatic pressure tests above 5000 psi to validate structural integrity under peak conditions. Sleek smooth bore design eliminates dead legs that can trap fluids, reducing contamination risk and ensuring uniform flow.
Compatibility extends across a wide portfolio of Graco spray equipment, allowing direct installation on pump outlets, manifold blocks, and gun inlets. Flow dynamics remain stable as the straight configuration prevents abrupt directional changes. Users can mix and match connectors without adapters, streamlining inventory and cutting maintenance complexity. Smooth transition from tube to thread prevents eddy currents and maintains consistent flow velocity across bends and fittings. Quick-connect couplings can be fitted at either end for rapid disassembly, enabling field service technicians to swap components in minutes. Precise machining preserves hose life and prevents fatigue in vibratory or mobile applications.
Inspect mating threads for debris and apply a suitable sealing compound or PTFE tape to the male interface only. Hand-thread the fitting until initial engagement, then use a calibrated torque wrench to tighten within the recommended 20–30 ft-lb range. Avoid over-torquing to prevent distortion of tube ends. After installation, ramp system pressure gradually and verify joint integrity through a leak-check. Plan follow-up inspections soon after start-up and at regular intervals when handling abrasive or particulate media.
Periodic monitoring of sealing surfaces and thread condition preserves performance over extended intervals. In abrasive environments, flush with compatible solvents to remove deposits that could abrade mating components. Replacement schedules should align with service cycles and media composition. For enhanced uptime, consider value-added graco sprayer accessories engineered to simplify preventive maintenance. Specialists can advise on retrofit kits, upgrade paths and optimization routines tailored to production demands.
Outer diameter of 6.35 mm and internal bore of 4.75 mm ensure optimal flow. Male thread is 18 TPI conforming to 1/4NPT standard. Rockwell B hardness of 85 provides strength against vibration and repeated connect cycles. Unit weight near 15 g minimizes load on spray heads or robotic arms. Compatible with waterborne paints, solvent coatings, adhesives and lubricants. Integration with genuine graco pump parts sustains stable pressure and peak efficiency.
Automotive, aerospace, and industrial manufacturers rely on this fitting tube for tasks ranging from high-volume spray painting to precision adhesive metering. Corrosive bath and chemical injection systems benefit from its stainless steel construction and smooth bore profile, which resists clogging. In sealant dispensing operations, it maintains laminar flow to ensure bead consistency. Laboratory and research setups can integrate it in fluid analysis apparatus without concern for metallic contamination thanks to the electropolished finish. With compatibility across multiple Graco modules and third-party manifolds, versatility extends to robotic paint cells, manual spray wands, and custom fluid networks in specialized production lines.
Reliable connectors are critical in industrial spray operations, where consistent fluid delivery impacts coating quality and throughput. Straight 1/4NPT fittings reduce inventory complexity and speed field servicing. OEMs and service engineers trust components built to strict quality and certification standards to ensure compliance and minimize rework.
